DETAILED DESCRIPTION

The following description and the drawings sufficiently illustratespecific embodiments to enable those skilled in the art to practicethem. Other embodiments may incorporate structural, logical, electrical,process, algorithm, and other changes. Portions and features of someembodiments may be included in, or substituted for, those of otherembodiments. Embodiments set forth in the claims encompass all availableequivalents of those claims.

IEEE 802.11ax enables operation at 6 GHz. As part of the agreements, itwas mandated that station devices (STAs) have to respect transmit powercontrol by the access point (AP) by using the legacy protocols alreadydefined (for instance for dynamic frequency selection (DFS) at 5 GHz).

The characteristics in the 6 GHz band as compared to 2.4/5 GHz are thefact that incumbent services are present at the 6 GHz band. For example,Fixed Satellite Service (FSS) uplink in 5925-7075 MHz, Fixed Servicepoint-to-point microwave in 5925-7125 MHz, Mobile—transportablebroadcast at 6425-6525 MHz and 6875-7125 MHz. The bands used byincumbent services are fixed, and the services are turned on and off inthe long term. A database (automated frequency coordination (AFC)) maybe defined to include the bands used by incumbents in the 6 GHz band.This database tells APs which channel is used by the incumbent. Thedatabase could be maintained by a network operator. The AP maycommunicate with the database by sending messages to request informationassociated with channel allocation for incumbent services before makingdecisions of allocating resources to Wi-Fi devices. This communicationbetween the AP and the database could be periodic or happen atpredetermined times or requested by a system administrator.

There are some differences between rules for 5 GHz APs and 6 GHzindoor-outdoor APs. The AFC and listen-before-talk (LBT) rules. AFC is adatabase of existing networks using licensed frequencies in the 6 GHzband. Licensed 6 GHz networks could be a site-to-site wireless link,mobile network or perhaps satellite link. Licensed frequencies areowned, and thus cannot be compromised by unlicensed devices operating onthe same frequencies. AFC compliant APs will have to search the AFCdatabase and blacklist any channels that are used by nearby licensedfrequency deployments.

The AP can send a Power Constraint Element or a Transmit Power EnvelopeElement that describes the maximum allowed transmit power by the STA,which is either defined to respect regulatory rules, or simple transmitpower control by the AP.

Lately, the Federal Communications Commission (FCC) has published itsReport and Order document that details the rules it intends to apply foroperation at 6 GHz.

As part of this, 2 modes of operations are defined for APs:

Standard-power APs (SP APs), that need to communicate with AFC operatorsto be given, based on the AP's location, the allowed channels within the6 GHz spectrum (within UNII5 and 7), and the power constraints on thesechannels.

Low power indoor APs (LPI APs), that do not need to communicate with AFCoperators, that simply have to operate indoors, and respect moreconstrained transmit power rules (lower power), but can operate on anychannels in the entire 6 GHz spectrum.

Depending on whether the AP operates as an SP AP or as an LPI AP, itsassociated STAs have to respect different rules.

The FCC created PSD limits for indoor-only 6 GHz channels which allowAPs using channel widths of at least 80 MHz to function normally, butthat restrict the performance of APs which use channel widths of 20 or40 MHz.

Associated with an SP AP, the STA will have a PSD (power spectraldensity) limit of 17 dBm/MHz, and a max EIRP transmit power of 30 dBm.These constraints can be more severe in presence of incumbents (PSD andEIRP can be lowered).

Associated with an LPI AP, the STA will have a PSD limit of −1 dBm/MHz(whatever its bandwidth). It is still somewhat unclear if the STA is notassociated with the AP, if it would have to comply with some powerlimits for pre-association traffic (probing, . . . ). Currently, thereis no defined way for the AP to tell the STA which PSD limit to use.Because of that, the STA cannot determine if it can use the power limitsfor standard power or for low power indoor.

There is a need also to provide PSD limits and Max transmit power for 2types of STAs:

a. Regular clients that have to transmit 6 dB lower than AP.

b. Subordinate access points that can transmit at the TxPower of the AP:a device that operates in the 5.925-7.125 GHz band under the control ofan Indoor Access Point, is plugged into a wall outlet, has an internallyintegrated antenna, is not battery powered, does not have a weatherizedenclosure, and does not have a direct connection to the internet.Subordinate access points must not be used to connect devices betweenseparate buildings or structures. Subordinate access points must beauthorized under certification procedures in part 2 of this chapter.Modules may not be certified as subordinate access points.

Example embodiments of the present disclosure relate to systems,methods, and devices for power spectral density (PSD) limit for 6 GHz.

In one embodiment, a PSD limit system may define a way for the AP toprovide to an associated AP and to an unassociated AP the PSD limit onthat channel:

-   -   That field can be included in a new element called PSD limit        element, or more likely, can be included in the Transmit Power        Envelope element as a new field.

In one embodiment, a PSD limit system may facilitate that an AP thatoperates at 6 GHz shall provide the PSD limit in at least theassociation response frame, and it may be possible to mandate that inbeacons and probe responses that PSD limit can be given for eachsupported bandwidth, or on each segment within the bandwidth. Uponreception of this information, the STA shall respect the PSD limit onthe channels of operation of the AP that provided this information, inaddition to the other max transmit power rules, or at least whencommunicating with that AP.

In one or more embodiments, a PSD limit system may define a way for theAP to provide to an associated device (e.g., STA or AP) and to anunassociated device (e.g., STA or AP) the PSD limit and the maximumtransmit power (equivalent isotropically radiated power (EIRP)) on each20 MHz channel of the basic service set (BSS) operating bandwidth (BW),or on smaller subset of bandwidth (5-10 MHz). For example, an APoperating on 80 MHz can provide the PSD limit for each of the 20 MHzconstituting the 80 MHz. Based on that information, the STA has torespect the PSD limits on each 20 MHz channel. For instance, if it isscheduled for transmission of an UL TB PPDU in one particular 20 MHzchannel, the PSD limit and Max Transmit Power of that channel wouldapply to that transmission.

In one or more embodiments, a PSD limit system may define just a simplefield to indicate the type of AP (whether it is standard-power AP, orLow Power Indoor AP, or Very Low Power AP (if FCC allows that mode ofoperation). This field could be included in beacons/proberesponses/association responses/fast initial link setup (FILS) discoveryframe (DF), be included in Reduced Neighbor Report element or NeighborReport element. Thanks to this, the STA would be able to derive the maxtransmit power and PSD limits if they are clearly defined by regulation(for instance, for LPI AP, PSD is clearly −1 dBm/MHz). If included inthe RNR of a collocated AP reporting an AP operating at 6 GHz, the STAmay be mandated to respect the PSD limit even when transmitting proberequests before associating to the AP.

In one or more embodiments, a PSD limit system may allow the AP toprovide 2 set of power limits, one for regular STAs and one forsubordinate APs. It is proposed that the AP can include both PSD andEIRP TxPower limits for both regular STAs and Subordinate APs.

For instance, it would include one Transmit Power Envelope for regularSTAs for EIRP limits, one Transmit Power Envelope for regular STAs forPSD limits, one Transmit Power Envelope for subordinate APs for EIRPlimits, one Transmit Power Envelope for subordinate APs for PSD limits.

To reduce the overhead, a PSD limit system may define also a simple modewhere the AP provides (for instance in the Transmit Power Envelope) asingle field that indicates the additional power that Subordinate APscan use, the field can be called “increased Power for Subordinate APs”.Subordinate APs determine their Local Max Transmit power limit for BW Xby adding the value of the Local Max Transmit Power Limit for BW W fieldand the value of the Increase Power for Subordinate APs field. Withthis, the STA will not be forced to always operate with the lowest PSDlimit.

The above descriptions are for purposes of illustration and are notmeant to be limiting. Numerous other examples, configurations,processes, algorithms, etc., may exist, some of which are described ingreater detail below.

For example, one or moreAPs 102 may implement a PSD limit 142 with one or more user devices 120.It is understood that the above descriptions are for purposes ofillustration and are not meant to be limiting.

FIGS. 2, 3A, and 3B depict illustrative schematic diagrams for PSDlimit, in accordance with one or more example embodiments of the presentdisclosure.

The Transmit Power Envelope element conveys the maximum transmit powersfor various transmission bandwidths or channels within the bandwidth ofthe BSS. The format of the Transmit Power Envelope element is shown inFIG. 2 .

In one or more embodiments, a PSD limit system may facilitate includinga PSD limit information as shown in FIG. 2 .

The Local Maximum Transmit Power Per 1 MHz field defines the localmaximum transmit power spectral density limit for a PPDU of anybandwidth.

In one or more embodiments, if PSD limit for every BW (20/40/80/160/320MHz) it is to be included in Transmit Power Envelope element, then theinterpretation Unit subfield may need to be changed in the TransmitPower Envelope (e.g., transmit power information element in the TransmitPower Envelope element). In that case, the AP that wants to include bothTxPower limits and PSD limits would include 2 Transmit Power Envelopeelements, one for TxPower with the EIRP option in the Local MaximumTransmit Power Unit Interpretation field of the transmit powerinformation element, one for PSD limit with the PSD EIRP option in theLocal Maximum Transmit Power Unit Interpretation field of the transmitpower information element.

The Local Maximum Transmit Power Unit Interpretation subfield providesadditional interpretation for the units of the Local Maximum TransmitPower For X MHz fields (where X=20, 40, 80, or 160/80+80 MHz) and isdefined in Table 1 below.

TABLE 1 Definition of Local Maximum Transmit Power Unit Interpretationsubfield. Unit interpretation of the Local Maximum Transmit Value PowerFor X MHz fields 0 EIRP 1 PSD EIRP 2-7 Reserved NOTE- This table isexpected to be updated only if regulatory domains mandate the use oftransmit power control with limits that cannot be converted into an EIRPvalue per transmission bandwidth.

If the Maximum Transmit Power Interpretation subfield is 1 (PSD EIRP),the format of the Maximum Transmit Power field is shown in FIG. 3A.

The Maximum Transmit Power Count subfield determines the value of aninteger N as defined in Table 2 specifies the format and interpretationof the Maximum Transmit Power field as described below.

If N is 0, then the Maximum Transmit Power field contains one MaximumTransmit PSD subfield that represents the maximum transmit PSD for aPPDU of any bandwidth within the BSS bandwidth.

If N is greater than 0, then the Maximum Transmit Power field has Noctets, with N representing the number of 20 MHz channels for which amaximum transmit PSD is indicated. The X-th octet (X=integer rangingfrom 1 to N) of the Maximum Transmit Power field is the Maximum TransmitPSD X subfield, which indicates the maximum transmit PSD for the X-th 20MHz channel.

If the BSS bandwidth is 20, 40, 80 or 160 MHz, then the Maximum TransmitPSD 1-N subfields correspond to 20 MHz channels from lowest to highestfrequency, respectively, within the indicated bandwidth. If N is equalto 1, 2, 4 or 8 for 20, 40, 80 or 160 MHz BSS bandwidth, respectively,the indicated bandwidth is the BSS bandwidth. If N is greater than 0 andless than 2, 4 or 8 for 40, 80 or 160 MHz BSS bandwidth, respectively,then the indicated bandwidth is the primary 20 MHz, primary 40 MHz orprimary 80 MHz channel for N equal to 1, 2 or 4, respectively. If N isgreater than 1, 2 or 4 for 20, 40 or 80 MHz BSS bandwidth, respectively,then the indicated bandwidth is wider than the BSS bandwidth. In thiscase, the Maximum Transmit PSD 1-M subfields correspond to the 20 MHzchannels from lowest to highest frequency, respectively, within the BSSbandwidth where M is 1, 2 or 4 for 20, 40 or 80 MHz BSS bandwidth,respectively.

FIG. 3B addresses the issue of subordinate APs. Subordinate APsdetermine their Local Max Transmit power limit for BW X by adding thevalue of the Local Max Transmit Power Limit for BW W field and the valueof the Increase Power for Subordinate APs field. It is understood thatthe above descriptions are for purposes of illustration and are notmeant to be limiting.

FIG. 4 illustrates a flow diagram of illustrative process 400 for a PSDlimit system, in accordance with one or more example embodiments of thepresent disclosure.

At block 402, a device (e.g., the user device(s) 120 and/or the AP 102of FIG. 1 ) may generate a frame comprising one or more elements to besent to a first station device, wherein the frame is to be sent using a6 GHz band.

At block 404, the device may include in the frame, informationassociated with a power spectral density (PSD) limit on a per bandwidthsize basis of the 6 GHz band. The PSD limit may indicate to the firststation device to abide by the PSD limit on a per bandwidth size basis.The first station device may be an associated or unassociated device.The one or more elements may comprise an equivalent isotropicallyradiated power (EIRP). The information may indicate to the first stationdevice to send its uplink data using the PSD limit and the EIRP. Theinformation may be included in a transmit power envelope element of theframe. The frame may be a beacon frame, a probe response, or anassociation response. The information may be included in an reducedneighbor report (RNR) of a collocated access point reporting an APoperating at 6 GHz.

The mixer circuitry 902 and/or 914 may each,according to some embodiments, be configured to provide directconversion functionality. The latter type of circuitry presents a muchsimpler architecture as compared with standard super-heterodyne mixercircuitries, and any flicker noise brought about by the same may bealleviated for example through the use of OFDM modulation. FIG. 9illustrates only a simplified version of a radio IC circuitry, and mayinclude, although not shown, embodiments where each of the depictedcircuitries may include more than one component.

In some embodiments, the mixer circuitry 902 and the mixer circuitry 914may each include two or more mixers and may be arranged for quadraturedown-conversion and/or up-conversion respectively with the help ofsynthesizer 904. In some embodiments, the mixer circuitry 902 and themixer circuitry 914 may each include two or more mixers each configuredfor image rejection (e.g., Hartley image rejection).

Mixer circuitry 902 may comprise, according to one embodiment:quadrature passive mixers (e.g., for the in-phase (I) and quadraturephase (Q) paths). In such an embodiment, RF input signal 807 from FIG. 9may be down-converted to provide I and Q baseband output signals to besent to the baseband processor.

Quadrature passive mixers may be driven by zero and ninety-degreetime-varying LO switching signals provided by a quadrature circuitrywhich may be configured to receive a LO frequency (fLO) from a localoscillator or a synthesizer, such as LO frequency 905 of synthesizer 904(FIG. 9 ). In some embodiments, the LO frequency may be the carrierfrequency, while in other embodiments, the LO frequency may be afraction of the carrier frequency (e.g., one-half the carrier frequency,one-third the carrier frequency). In some embodiments, the zero andninety-degree time-varying switching signals may be generated by thesynthesizer, although the scope of the embodiments is not limited inthis respect.

In some embodiments, the LO signals may differ in duty cycle (thepercentage of one period in which the LO signal is high) and/or offset(the difference between start points of the period). In someembodiments, the LO signals may have an 85% duty cycle and an 80%offset. In some embodiments, each branch of the mixer circuitry (e.g.,the in-phase (I) and quadrature phase (Q) path) may operate at an 80%duty cycle, which may result in a significant reduction is powerconsumption.

The RF input signal 807 (FIG. 8 ) may comprise a balanced signal,although the scope of the embodiments is not limited in this respect.The I and Q baseband output signals may be provided to low-noiseamplifier, such as amplifier circuitry 906 (FIG. 9 ) or to filtercircuitry 908 (FIG. 9 ).

In some dual-mode embodiments, a separate radio IC circuitry may beprovided for processing signals for each spectrum, or for otherspectrums not mentioned here, although the scope of the embodiments isnot limited in this respect.

In some embodiments, the synthesizer circuitry 904 may be a fractional-Nsynthesizer or a fractional N/N+1 synthesizer, although the scope of theembodiments is not limited in this respect as other types of frequencysynthesizers may be suitable. For example, synthesizer circuitry 904 maybe a delta-sigma synthesizer, a frequency multiplier, or a synthesizercomprising a phase-locked loop with a frequency divider. According tosome embodiments, the synthesizer circuitry 904 may include digitalsynthesizer circuitry. An advantage of using a digital synthesizercircuitry is that, although it may still include some analog components,its footprint may be scaled down much more than the footprint of ananalog synthesizer circuitry. In some embodiments, frequency input intosynthesizer circuitry 904 may be provided by a voltage controlledoscillator (VCO), although that is not a requirement. A divider controlinput may further be provided by either the baseband processingcircuitry 708 a-b (FIG. 7 ) depending on the desired output frequency905. In some embodiments, a divider control input (e.g., N) may bedetermined from a look-up table (e.g., within a Wi-Fi card) based on achannel number and a channel center frequency as determined or indicatedby the example application processor 710. The application processor 710may include, or otherwise be connected to, one of the example securesignal converter 101 or the example received signal converter 103 (e.g.,depending on which device the example radio architecture is implementedin).

In some embodiments, synthesizer circuitry 904 may be configured togenerate a carrier frequency as the output frequency 905, while in otherembodiments, the output frequency 905 may be a fraction of the carrierfrequency (e.g., one-half the carrier frequency, one-third the carrierfrequency). In some embodiments, the output frequency 905 may be a LOfrequency (fLO).

FIG. 10 illustrates a functional block diagram of baseband processingcircuitry 708 a in accordance with some embodiments. The basebandprocessing circuitry 708 a is one example of circuitry that may besuitable for use as the baseband processing circuitry 708 a (FIG. 7 ),although other circuitry configurations may also be suitable.Alternatively, the example of FIG. 9 may be used to implement theexample BT baseband processing circuitry 708 b of FIG. 7 .
